A case of carcinoid tumor in the accessory papilla of the duodenum

Abstract

We report a resected case of carcinoid tumor located in the accessory papilla of the duodenum. A 42-year-old man was found to have a tumor in his duodenum ; a diagnosis of carcinoid was made based on a biopsy specimen. Pylorus-preserving pancreaticoduodenectomy was performed. The resected specimen contained a tumor that was 18mm in size, which was located in the accessory papilla of the duodenum ; on histopatholoy, lymph node metastases were found.
This is the fourteenth reported case of carcinoid tumor in the accessory papilla of the duodenum. Eleven of these cases had positive lymph nodes, although the tumors themselves were small. This suggests that radical surgery with regional lymph node resection is useful for treating patients with this disease.
